EE230: Signals & Systems

EE230, Signals and Systems, introduces the Fourier and Laplace transforms as methods to model and analyze continuous-time linear systems (primarily first and second-order circuits) in the frequency domain. Parallels between the time and frequency domains are discussed, and sampling and filter design issues are developed. The course makes extensive use of Matlab as a computational and visualization tool. Labs reinforce theory and develop hardware skills. Prerequisites: EE 223 and MA311. (3 lecture hours)
